Ok.

Register a hook to be ran every time any option of the blog is
changed. This hook must run a MySQL query that will update other
tables on other wpmu installations.

I would preffer to separate the script in one external file to be
fetched (e.g. with curl) by this hook, so you don't need to keep
updating passwords and IPs on every host.

An independent cron job would be more appropriate since this operation
may take a little time to be completed, but it's an expensive task
anyway.

Update just the desired field would be much better, and I'm not sure
how to do that, or even if that's possible with current Wordpress
structure.
